The size of the door should be made with such dimension so that it becomes possible to move the largest object through the doors.

For residential buildings, the size of the door should start from 0.9 m × 2.0 m and over. Larger doors are built up at the core entrance to the building to make view elegant. Minimum sized doors are suitable for bath rooms and water closets. The proposed size is 0.75 m × 1.9 m. As a thumb rule height of door should have been 1 m over and above its width.

Types of Doors – Different types of doors are available which are categorized based on the disposition of shutters, construction processes, precepts of working operations and materials employed. Detailed information is given below for the doors which are frequently used in the buildings:

  1. Battened and Ledged Doors: Battens are 100 mm to 150 mm large and made with 20 mm dense wooden boards. Their length is that of door opening. The battens are tied with horizontal planks, which are called as ledges of size 100 to 200 mm large and 30 mm thick. Generally, three ledges are employed one at top, one at bottom and the third one at mid-height. This is the easiest form of door and the economical also. Battens are fastened with tongued and grooved joint.
  2. Battened, Ledged and Braced Doors: If doors are wide except for applying battens and ledges diagonal members, identified as braces, are used to make the door toughen.

Periodically, above two types of shutters are supplied inside wooden frame work and in those cases they are named as battened, ledges and framed doors.

  1. Framed and Panelled Doors: This type of door comprises of vertical members, known as styles and horizontal members known as rails. The styles and rails are properly grooved to obtain panels. The panels may range from wood, A.C. sheet, glasses etc. The panels are flat or of raised type for having good appearance. These doors are used extensively. They are made of single shutter or of double shutter. If glass panels are employed they are known as glazed doors.

Types of footings with diagrams

This is a nice video presentation from Parag Pal, the renowned civil engineer. In this video, Mr. Parag gives brief explanation about types of footings mostly utilized in construction. The types of footings range from isolated footings, mat footings, strap footings, combined footings. All the footings are demonstrated with their diagrams.

Footings are considered as the most vital parts in various foundations like bridges.

Isolated footings – Isolated footings are used in normal home, house constructions. When footing is arranged to provide support to a distinct column, it is known as “isolated footing”. It belongs to circular, square or rectangular slab having identical thickness.

Combined footings – When two or more columns in a straight line are passed on a single spread footing, it is known as a combined footing. It is generally utilized when the two column are very adjacent to each other so that their individual footings would coincide.

Strap footings – A strap footing is a constituent of the foundation of a building. It is one sort of combined footing that contains two or more column footings attached with a concrete beam. This type of beam is known as a strap beam.

Mat/Raft foundation or mat footings – A big, dense, generally reinforced concrete mat that delivers loads from various columns and walls, to the foundational rock or soil. It is called raft foundation.

Benefits of Mivan Aluminium Formwork System for construction sectors

Formwork belongs to either temporary or permanent die or molds into which fresh concrete or equivalent materials are poured to solidify later. Lots of time are required for the development of formwork. It comprises expenditure up to 20 to 25% of the cost of the structure or all the more. Design of these temporary structures is created in an cost-effective way. The procedure for eliminating the formwork is called stripping. Stripped formwork is reusable. Reusable forms are called panel forms and non-usable are known as stationary forms.

Timber is mostly recognized as material for formwork. The main drawback with timber formwork is that it bends, expands and shrinks easily . To overcome this issues MIVAN Formwork can be used to get rid of the issue.

MIVAN ALUMINIUM FORMWORK: A European construction company has created Mivan aluminium formwork system. The product is very cost-effective and suitable for the entire construction world.

Variation among Plastering and Pointing

Plastering: Plastering is the process for using mortar coats on the exterior of walls, columns, ceiling to provide a sleek finish. Mortar that is utilized in plastering may range from lime mortar, cement mortar or lime-cement mortar. Lime mortar that is utilized should contain fat lime to sand ratio of 1 : 3 or 1 : 4. If hydraulic lime is applied, it’s mix ratio (lime: sand) is 1 : 2. Cement mortar of 1 : 4 or 1 : 6 mix is mostly utilized for plastering, richer mix is applied for outside walls. Lime-cement mortar is the combination of lime mortar and cement mortar in the ratio of (cement : lime : sand) 1 : 1 : 6 or 1 : 1 : 8 or 1 : 2 : 8. Lime-cement mortar can save significant plastering cost.

Lime mortar is generally applied in 3 coats whereas cement mortar is used in two or three coats toward the stone and brick masonry. Cement mortar is used in two or three coats toward concrete surfaces.

Most often, one coat of cement mortar is used for concrete building blocks.

The first coat is useful for attaining level surface. The final coat produces smooth surface. When three coats are applied, second coat is called floating coat. The average density of first coat is 10 to 15 mm. The density of middle coat is 6–8 mm. The density of final coat is just 2 to 3 mm. When single coat is applied, the density remains among 6 to 12 mm. Such coats are useful for concrete surfaces not uncovered to rain.

Pointing: In some cases, special mortar finishing work is applied to the uncovered joints in place of providing plaster to the whole surface of the masonry. It is known as pointing. It comprises of slanting the joints to a depth of 10 mm to 20 mm and stuffing it with richer mortar mixes. Toward lime mortar, the ratio of pointing mix is 1 : 2 and for cement mortar pointing mix is applied in the ratio of 1 : 3. Pointing is mostly suitable for stone masonry as stones contain eye-catching colors and strong resistance power against water penetration. Pointing makes weaker part of masonry (i.e. to joints) more accurate and it enhances the aesthetic view of the masonry.

Given below, some points of variations among plastering and pointing.

How to study column footing drawing for a structure

This construction video offers detailed guidelines on how to check column footing drawing.

Footings stand for structural elements which deliver the loads of column or wall to the elementary soil underneath the structure. Footings are built up to disperse these loads to the soil devoid of surpassing its safe bearing capacity, to resist enormous settlement of the structure to an acceptable limit with the purpose of reducing differential settlement as well as withstanding sliding and overturning.

The settlement is dependent on the depth of the load, nature of soil, and foundation level. If there is differential settlement, the different footings have to be designed in such a manner to settle self-reliantly of each other.

Foundation design comprises of a soil study to set up the most suitable type of foundation and a structural design to find out footing dimensions and necessary amount of reinforcement. As the compressive strength of the soil is normally much weaker as compared to the concrete, the contact area among the soil and the footing is much bigger with regard to that of the columns and walls.
